IMPROVEMENT IN BARBED -WIRE FENCES.

Specification forming part of Letters Patent No. 189,994, dated April24, 1877 application filed January 19, 1877.

To all whom it may concern:

Be it known that I, ADELBERT E. BRON- SoN, of Chicago, in the county ofCook and State of Illinois, have invented. certain new and usefulImprovements in Barbed-Wire Fences; and I do hereby declare thefollowing to be a full, clear, and exact description after more fullyset forth.

In order to enable others skilledin the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstrnctionand operation, referring to the annexed drawing, which formsa part of this specification, and in which Figure 1 shows my inventionas applied to Fig. 2 shows the same applied to double-twisted wires.

A and B represent two pieces or sections of wire, having their ends bentto form loops D and D respectively, and connected together in thefollowing manner: The straight part of the wire A passes through theloop D of the wire B, and the wireA then forms the loop D around thestraight part of the wire B. The end of the wire A is then passed inbetween the two wires A and B, and projects to one side, as In likemanner the end of the wire B, after it has formed the loop D is passedin between the wires A and B, and projects in the opposite direction.When thus placed in position, the short ends 0 G of the wires lie sideby side and parallel with each other. When any tension is applied to thewires A' and B, it will be evident that the loops will draw together,and as each loop has a small amount of elasticity, the number in theaggregate in the wires, when put up, will be sufficient to counteractthe contraction in cold weather, and, when properly put up, will havesufficient tension to keep tight in hot weather.

The elasticity in the wire, also, will prevent the wire from becomingbroken or otherwise injured if cattle or other stock should run againstor strain it in any manner.

In Fig. 2 I have shown thesame invention applied to two wires twistedtogether. In that case the loops and barbs will alternate in the twolengths of wires.

It will thus be seen that while the wires have, by the peculiarformation of the loops, all the elasticity required, yet the wires areso completely locked together that they cannot by any possibility bedrawn apart.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isf In a wire fence, the wires A andB, bent to form, respectively, the loops D and D and barbs O and O andunited together by the straight part of each wire passing through theloop of the other, and the barbs passing between the wires in oppositedirections, and lying side by side, substantially as herein shown anddescribed.
